Heavyweight concrete

Typically using barites the density will be in the region of 3,500kg/m 3, which is 45% greater than that of normal concrete, while with magnetite the density will be 3,900kg/m 3, or 60% greater than normal concrete. Very heavy concretes can be achieved with iron or lead shot as aggregate, 5,900kg/m 3 and 8,900kg/m 3 respectively.

High Density Concretes for Radiation Shielding

In contrast with conventional concrete weighing around 150 pounds per cubic foot, high-density concretes normally weigh from 200 to 250 pounds per cubic foot. Among the natural aggregates most commonly used are barite, magnetite, limonite, geothite, and ilmenite. These can be used for the lower and medium weight ranges.

Density vs Strength | basalite-cmu

In Northern California, most local aggregates are light and medium, therefore, most CMU in Northern California is produced as Lightweight and Medium Weight, while Normal Weight is used less frequently. Industry Classification of Density (weight) for Concrete Masonry (as determined by the weight of one cubic foot of the mix design used in a block):

High Strength, High Density Concrete

However, when space is a consideration, high density concrete can be used for shielding. Most high density concrete for shielding has been made with naturally occurring iron ores, titanferous iron ores, hydrous iron ores, and barite. Although structural strength is an important factor in high density concrete, workability and density have been ...

High Density Concrete

Nov 16, 2014 · High density concrete is a concrete having a density in the range of 6000 to 6400 kg/cu.m. High density concrete is also known as Heavy weight concrete. High density concrete is mainly used for the purpose of radiation shielding, for counterweights and other uses where high density is required. The high density concrete has a…

Concrete Density - an overview

When light-weight concrete (density ρ = 500∼1900 kg/m 3) is used for the structure to replace ordinary concrete, the weight of the structure with the same load-carrying capacity is reduced by 20–40%. This is an effective and easy way to deduce dead load of the structure.
